Pet stores can have vastly different numbers of animals depending on:
* Size of the store: Larger stores have more space for more animals.
* Types of animals: Some stores specialize in certain animals (like fish or reptiles) while others have a wider variety.
* Local regulations: Some areas have limits on the number of animals a store can hold.
To find out how many pets are in a specific pet store, you'd need to contact them directly or visit in person.
